  2. 1 Ocean tides …. A natural resource. By: Mrs. Benton

  3. 2 What is it? Ocean tides are a perpetual resource. Ocean tides occur because of the sun and moon’s gravitational pull on our planet. Each day there are two high tides and two low tides.

  4. 3 History The first tidal energy plant was built in 1966 near in France. This spot was used because it has extreme high and low tides. The first plant was started in 1925, but due to lack of money, the project was abandoned. Use of tidal energy was not a new idea. Dammed water turned paddle wheels and transformed that energy to grind wheat hundreds of years ago.

  5. 4 How it works... Tidal barrages (or dams) trap water at high tide. As the water rushes out at low tide, it spins the turbines. The spinning turbines turn the shaft in the generator which transforms the mechanical energy into electrical energy..

  6. 4 Ocean Tides We transform the kinetic movement of ocean tides into electricity by using turbines.

  7. 5 Used most? • France has the largest tidal energy plant in the world. • Canada built another tidal energy plant • near Nova Scotia in 1982.

  8. 6 Advantages..... 1. It is a perpetual resource. 2. Once built the energy is free. 3. Does not pollute the atmosphere.

  9. 7 Disadvantages..... 1. Can only be built in areas with extreme high and low tides. 2. Damming of areas can change ecosystems.

  10. 8 Interesting fact Interesting facts….. The highest tides in the world are at the Bay of Fundy in Nova Scotia, Canada. Highest tide recorded was 54 feet.
